Lemon Queen Helianthus is excellent for attracting birds, and butterflies Grown from Lemon Queen Sunflower seeds, this impressive annual produces a central stalk and blooms up to 12 inches and then produces several side shoots each with their own lemon yellow blooms. Sunflower Lemon Queen gets between 60 - 72 inches tall and will produce blooms in about 100 days after sowing the Sunflower seeds.
Grow Lemon Queen Sunflowers in a sunny location in somewhat fertile well-drained soil. Keep soil weed free and moderately moist while plants are young. Once established, Sunflower plants are somewhat drought and heat tolerant. They will flower mid-summer through fall.
After danger of frost has passed, directly sow Lemon Queen Sunflower seeds into prepared seed beds that are weed free and the soil has been loosened. Space the Sunflower seeds 6 inches apart, cover the seed 1 - 1/2 inch deep, and thin the Sunflower seedlings to 12 - 18 inches apart. Fertilizer should coincide with plants needs. If needed apply fertilizer at a rate of 2 - 2 1/2 lbs of actual nitrogen per 1,000 square feet as a side dressing before the plants reach 12 inches in height.
